Embodiment Construction

[0052] The development process of the wireless multimedia sensor network data management system based on the state machine is as follows:

[0053] Step 1: Perform requirements analysis to determine user interface parameters and query task definitions. First of all, the task needs to be completed according to the needs, and the input interface form and parameters of the query should be clarified. The input interface of the query is provided to the user through a graphical interface, and the parameters of the query are provided to the user, including the target node or target area of ​​the query, the content attribute of the query (video, audio, etc.), the accuracy of the query (high precision, low precision ), the timeliness of the query (instant information query, historical information query), etc.; secondly, determine the release method of the query task. The query task is sent to the target node or target area for execution by using different data packet formats based on di...

Abstract

The invention discloses a data management system based on a state machine, which is a data searching and management proposal in a wireless multimedia network, and is mainly used for solving data acquisition and data processing problems in the wireless multimedia network. A data management system in a wireless multimedia sensor network based on the state machine is developed and characterized in that: a search task is formed by various parameters through combination and encapsulation and different search applications are corresponding to different parameter combinations; the functions of network nodes are controlled by the state machine and the function decision of nodes depends on the current state; a primary search task is collaboratively fulfilled by multiple nodes in various states; the whole network has nodes in various states during the life cycle of the network and the same node can only be in one state at a specific time and the state of a node can change with the change of self conditions and transfer from one state to another; nodes of various states can carry out a routing strategy flexibly according to the timeliness and precision requirements of the search task.

Description
